DTC Code DTC Name
01-DC Transmission Error

DESCRIPTION

DTC No.

Detection Item

DTC Detection Condition

Trouble Area

01-DC

Transmission Error

Transmission to the component shown by the sub-code failed (Detecting this DTC does not always mean actual failure).

If the same sub-code is recorded in other components, check harness for power supply and communication system of all components shown by code

Tip:

This code may be stored if the engine is started and idled for 60 seconds and then the engine switch is turned to the start position again.

Note:
  • Before starting troubleshooting, be sure to clear DTCs to clear codes stored due to the reasons described in Hint above. Then, check for DTCs and troubleshoot according to the output DTCs.

  • The radio receiver assembly is the master unit.

  • Be sure to clear and recheck DTCs after the inspection is completed to confirm that no DTCs are output.

CAUTION / NOTICE / HINT

Note:

Be sure to read Description before performing the following procedures.

PROCEDURE

  1. CHECK FOR DTC OF OTHER COMPONENTS

    1. Check if the component shown by the sub-code is displayed in the check result of the other components.

      1. Check if "01-DC" is output for the other components.

      2. If "01-DC" is output for any other components, check if the same physical address is displayed.

        Tip:

        For the list of the components shown by sub-codes, refer to the table in the next step.

      Tip:

      If "01-DC" is output for only one component, this may not indicate a malfunction.

    2. Check for DTCs and check if the same trouble occurs again.

      OK

      The malfunction disappears.
